Please excuse me if i am being a complete dumb-ass here, but can't you just use google translator to translate each txt file? Like, i just loaded one of them up, and obviously it was all in japanese but i used google translate as im using google chrome so it asks if i would like totranslate the page. Cant you just do that for each one? You'd be dont in like an hour? BTW i hardly know anything about this, so dont be all raw raw if its more complicated lol.
